Floor topping, trowel applied, high build epoxy
resin system (5 mm thickness)
Uses
Durafloor TF has been designed for the on-site
manufacturing of a 5 mm thick Durafloor TF screed in
environments where high resistance to mechanical and
chemical attack is required. Typical areas of use include
engineering plants, chemical plants, traffic aisles and food
processing areas. It may be sealed with Durafloor N
(Novolac) in areas of significant risk from chemical attack
(see separate Technical Data Sheet).
Advantages
 Suitable for application in food preparation areas
 Durable - provides long-term protection in heavy
industrial environments
 Improves efficiency - seamless surface aids traffic flow
and cleaning
 Good resistance to a wide range of industrial chemicals
 Tough - resists high impact and point loading
Description
Durafloor TF Binder is a two-part low viscosity epoxy resin
system to which Durafloor TF Fillers and a Durafloor colour
pack can be added to produce the trowellable epoxy mortar
(Durafloor TF) for the installation of a high performance
industrial floor system.
Durafloor TF when laid, produces a matt, slightly textured
anti-slip floor system.
Durafloor TF can be overcoated to provide different non-slip
and sealed properties. The product can also be produced in
a range of standard colours.
Technical Support
Parchem offers a comprehensive range of high performance,
high quality flooring, jointing and repair products for both new
and existing floor surfaces. In addition, the company offers a
technical support package to specifiers, end-users and
contractors, as well as on-site technical assistance.

Chemical properties
Durafloor TF has excellent resistance at ambient
temperature to a wide range of industrial chemicals.
Note that it is especially important that spillage is cleared up
since very much higher concentrations of chemicals may
occur on evaporation.
Maintenance
The service life of a floor can be considerably extended by
good housekeeping. Regular cleaning of Durafloor TF may
be carried out using a rotary scrubbing machine with a water
miscible cleaning agent or by hot water washing at
temperatures up to 60°C.
Application Instructions
Durafloor TF should be installed by specialist applicators who
must follow the application instructions. The following steps
are involved in the application which would normally take
place over a 3 - 5 day period.
Preparation
Correct surface preparation is essential to achieving bond
between the substrate and the new floor. All concrete should
be sound, clean, dry and free from contaminants. Hydro
blasting, captive shot blasting or grit blasting equipment is
necessary to ensure that adequate substrate preparation is
achieved. On small areas, needle gunning or bush
hammering is acceptable. The parent concrete should have
a minimum compressive strength of 25 MPa and be free of
any weak surface laitance.
Priming
All substrates on completion of the preparation are to be
primed with Durafloor TF Binder or Nitomortar 903.
More than one coating may be required depending on the
porosity of the substrate. For where high build applications
are required on vertical systems seeding the wet primer with
a suitable grit will prevent the screed coat from sliding.
